Re: xen guest not booting

[-- Attachment #1: Type: text/plain, Size: 23000 bytes --]

This is a disk read problem.
Are you seeing this messages within the guest? In that case it might be
a problem with your backend.
What is your dom0 kernel? Is this a PV or an HVM guest?

Re: [Xen-devel] xen guest not booting

[kishore kumar]

[-- Attachment #1.1: Type: text/plain, Size: 23578 bytes --]

I am seeing this problem while booting the guest.  The guest is a HVM.
My xen is 3.4.3-rc4-pre, and Dom0 kernel is 2.32.10 .
The dom0 boots perfectly fine.  While booting the HVM guest, I see hda
dma_timer_expiry dma status == 0x21 message on the linux shell and the
messages I posted earlier on my serial console.
Please suggest if anything can be done.

Thank YOu.

dom0 and the guest uses the same hard disk with partioned.

guest uses the command disk = [ 'phy:/dev/VolGroup01/hvm, hda, w'  ]

I did not move the partition.

Make a new one and copy (dd) the guest in that and see if the problem shows up.
